Electrostatic Charge: Chemical Polarity & Charging Materials

[Passionate Eng]

Someone told me that dust can not be charged because it does not have chemical polarity.
Is that right?
Should materials have chemical polarity to be charged?

Dust particles can be charged, and this is completely independent of their chemistry.
Who is "someone"?
